v1.2.0:7 — add SparkControl AI provider + fix base-URL footgun

SparkControl is a self-hosted local-inference gateway with an OpenAI-compatible API, reached over the internal same-box StartOS address (http://spark-control.startos:9999/v1, plain HTTP). It takes no API key, so generateOpenAIStyle gained a { requireApiKey } option and now omits the Authorization header when no key is set. The Settings form auto-detects the loaded vLLM model via SparkControl's /api/endpoints probe, mirroring the Ollama auto-detect; it's $0 in the cost UI. Custom-URL => admin-only + SSRF-guarded, same as Ollama.

Also fixes a config footgun behind the empty-response report: a custom base URL could ride along to a fixed-URL provider (claude/openai/gemini) whose form field is hidden, get stored, and be silently ignored (the provider always hits its hardcoded endpoint). Both config write paths now null baseUrl for non-custom-URL providers, and the form clears it on provider change.

No schema/data change (AIConfigProfile.provider is free-text). 259 tests pass; built + sideloaded to immense-voyage.local with a clean non-root launch.
